I went for my first scan yesterday, they didn’t give me a copy because apparently I’m still to early?

My app tells me I’m 7 weeks 3 days according to my lmp 20/09/18.

The technician measured my sac being 5 weeks and 2 days, yolk sac was there and baby was there. I thought I saw a blinking flutter but she didn’t ask if I wanted to hear the heartbeat and left it as that. She’s asked me to come back in 2 weeks to check if the baby’s grown. I’m so disappointed.
